Update helm chart cert-manager to v1.20.3

Single-pod sqlite install (simplest path for a home git host). HTTPS-only,
no SSH listener for now. Wired into the Hetzner tunnel like the other
rubenhensen.nl services.

First visitor to git.rubenhensen.nl can register; Gitea auto-promotes the
first user to admin.
